Letters Patent No. 108,321, dated October 18, 1870 antedated October 1, 1870.

IMPROVEMENT IN ECX-SCRAPERS.

ww-M The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents may come:-

Be it known that I, J Lurns RICHARDSON Bnown, of 'Oambridgeport, of the county, ot' Middlesex and State ofh/Iassaehusetts, have made a new and useful invent-ion having reference to Box-Scrapers and do hereby declare the same to be fully described in the following specification, reference beingvh'ad to the accompanying drawing making part thereof'.

\ Ot' such drawing- Figure l is a top view;

- Figure 2, a longitudinal section;

Figure 3, a side elevation; and

Figure 4, a frontend View oi' one of my improved Scrapers.

This scraper, though somewhat analogous to that for wliicli`Lctt`ers latent I\'o. 86,741 were granted February t), 186i), to Willi-.un Dutton, ot' Bestell, of' the State of lllassaehusetts, yet ditlers materially therefrom, inasmuch as in my improvedscraper there is a.' cap to the cutter, and such cap is united to the handle; whereas, in the scraper ot' Dutton, there is no such cap.

The said cap is to perform the function of the capironef 'a joincrs plane.

Furthermore, in my scraper' the screw by which the cutter is held in place goes through the stock and the cutter, :md screws up into the shank ofthe handle, the same admitting.,v of the screw beingmademueh longer and stronger than the screw as used in the scraper ot' D Litton, as such screw simply goes through the cutter, and the stock receives a lever-nut on the outside ofthe stock.

The lever-nut, owing to its'position, is liable to de- 4 rangement, but in my scraper the screw-head is on the outside ofthe stock, and there is no nut required to hold the cutter' to the stock.

The screw in my scraper contines the stock and eutter together, and to the cap and handle.

In the drawing- A denotes the stock B, the cutter;

O, the cap;

I), the handle; and l a, the shank et' such handle.

The steek is formed with a bearing-surice, b, haring a throat, e, made through it, such bearing-surface being arranged at an obtuse angle with the front face ofthe stock.

From the inner taee et' the stock two lips, cl d, project parallel to each other. They serve as guides and supports for the cutter or plane-iron B, which is disposed between them and in the throat, in manner as represented. l

- The eap C is in one piece with or directly attached to the shank a ofthe handle.

The screw for connecting the stock to the cap and handle, and confining the cutter between them is represented at E. It goes through a hole in the stock, and also through a slot in the cutter, and screws into the cap and the shank, they serving to strengthen the connection of the said cap and shank, besides aecomplishing,r other duties, as hereinbefore Stated.

I make no claim to the subjectof the aforesaid patents; nor do I'claim a box-scraper made as represented in the United States patent numbered 41,571,01' as represented' in the specilcation and dra-wings ot' lieux-y, Joseph, and Thomas H. Belchers application t'or a patent, filed `in the Patent Othce June 6, 1862.

ln the scraper' ot' the patent 41,571, the mouthed stock and the handle are in one piece of metal, and the cutter is held by a clamp-plate, which in no respect performs, with the cutter, the office of a capiron, to turn the shaving and act in other respects like the cap-iron ot'a joiners plane, as does the cap C ot' 'my implement.

1n the said Belchcrs scraper there is no mouthed stock, as in mine, andv no cap-iron, the cutter being held in place by a screw projected from the shank ot the handle, and having a nut screwed on it.

The screw of my scraper goes through the stock and into the cap and shank, which is notthe ease with that ot' the said Belchers scraper.

What I claim as ot' my invention, in the improved scraper hereinbefore explained, is as follows:

.The arrangement, as described, of the cap C, projected from the shank (t, the stock A, provided with the mouth e, and made separate trom the cap O, the .eutterB and the screw E, the said parts, with the handle, constituting an improved box-scraper, for use as specified.

JAMES RICHARDSON BROWX.
